As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Researchers Just Spotted The 'World's Rarest Bird' in Brazil

DAVID NIELD
28 DEC 2018

After months of fruitless searching, one of the most endangered birds on the planet has finally been spotted once more.

It's not particularly flashy, nor large. Stresemann's Bristlefront is a medium-sized, long-tailed bird with distinctive bristles on its forehead - but scientists think there are only a handful of these creatures left in the world.

Two sightings of a female on December 12 and 14 have now given conservationists hope that it's not too late to save the bird from total extinction, as its rapidly dwindling rainforest habitat is threatening to push the population right down to zero.

Found only in a small region of eastern Brazil, Stresemann's Bristlefronts (Merulaxis stresemanni) were first noted in the 1830s. But it seems they were always an elusive sort.

After that initial spotting, it wasn't until the mid-20th century that another specimen was collected. The species got its name thanks to German-Brazilian ornithologist Helmut Sick, who noted both the bird's distinctive bristles and the name of his tutor Erwin Stresemann.

A name wasn't enough to keep the bird in our sights, though. It disappeared for another 50 years before another encounter in 1995 – which gives you some idea of just how rare it is to chance a look at this creature.

Say ‘no’ to extinction: saving Bristly and his fourteen companions

By Shaun Hurrell, Thu, 28/04/2016 - 12:38

Stresemann’s Bristlefront Merulaxis stresemanni: a long-tailed bird with distinctive forehead bristles, a rufous rump, a musical whistle song, seen perhaps eating frogs and insects, and with a tennis-ball-sized tunnel for its nest. Spotted a handful of times since its rediscovery in Brazil’s Atlantic forest in 1995, that’s about all we know of this unique bird. Apart from one scary fact: there are fewer than fifteen individual birds left of the entire species.

Some species cling to existence on mere scraps of remaining habitat until… they’re gone. And once they’re gone, there is no turning back. But while those few individuals resist we have a chance to save them. A chance we are not going to miss.

That is why, today, BirdLife International embarks on an ambitious new global initiative to prevent the extinction of endangered species including Stresemann’s Bristlefront, as part of the Alliance for Zero Extinction (AZE).

The multi-million dollar initiative teams-up coordinators BirdLife, the American Bird Conservancy, the Global Environment Facility, and the United Nations Environment Program with the governments of Brazil, Chile, and Madagascar – where projects to restore and protect AZE species’ habitat with community support will first be demonstrated.

AZE is a global initiative working to prevent species extinctions by identifying and safeguarding the places where Endangered or Critically Endangered species are restricted to single remaining, irreplaceable sites.

“Protecting the last remaining habitats for Critically Endangered species is a vital strategy for preventing extinctions,” said Braulio Dias, Executive Secretary of the UN Convention on Biological Diversity (CBD), with whom the initiative will work closely.

BirdLife is well-versed on Preventing Extinctions – to not save the rarest of the rare would be unthinkable. Saving these tiny habitats is saving entire species.

Stresemann’s Bristlefront habitat is a remnant strip of humid forest in a valley at the border of Bahia and Minas Gerais states, Brazil. Every day the sound of chainsaws firing up, the crackle of forest fires, and the smell of cow dung are getting ever closer. Rapid deforestation for logging, plantations and cattle ranching have devastated the state’s forest, which is a unique habitat-type (South American Atlantic forest) high in endemic species and of which only 10% of its original South American extent remains in Brazil. The ten individual birds are clinging to existence, stranded in an ‘island’ of forest.

With fewer than fifteen birds left – is it possible to save them?

First nest ever discovered of one of the world's most endangered birds


Stresemann's Bristlefront nest discovered in Brazil
January 2013. The first known nest of one of the world's rarest birds - the Critically Endangered Stresemann's Bristlefront - has been discovered in Brazil. Of perhaps equal significance is that strong evidence of active nestlings was also found.

Rediscovered in 1995 - May be just 15 birds alive
The Stresemann's Bristlefront is one of the world's most threatened bird species - unrecorded for 50 years until it was rediscovered in 1995 near Una, Bahia, in Brazil's Atlantic Forest region. The world population estimate is fewer than 15 individuals. Its population is declining owing to fires, logging, and the clearance of humid valley-floor forest for cattle ranching and agriculture.

Nest tunnel
On October 30, 2012, Dimas Pioli and Gustavo Malacco, two Brazilian researchers visiting Fundação Biodiversitas' Mata do Passarinho Reserve discovered the bird's nesting tunnel entrance, a tennis ball sized hole, located about three feet from the ground in an exposed dirt vertical edge that contained overhanging vegetation. Nesting tunnels are typical for the ground dwelling Tapaculo family, to which the Bristlefront belongs. The hole is estimated to be approximately six feet deep. It was surveyed and filmed with a micro-camera and further data should be published shortly in an ornithological journal.

Probable chicks
"This is the discovery of a lifetime made all the more gratifying by the fact that not only have we found live adult birds, but we have also found strong evidence of several chicks as well," said Alexandre Enout, the Reserve's Manager. "It is urgent that we protect more of the natural Atlantic Forest in this area and reforest areas where forest has been lost. The best way to save this species is by increasing its potential habitat."

The 8-inch long, medium-sized, long-tailed bird has distinctive, long, pointed forehead bristles and a slender dark bill. The female is cinnamon-brown above, with duskier tail and is a bright cinnamon-rufous below.
